A strand test is carried out in hairdressing to determine how a chemical treatment, such as hair dye or perm solution, will react on a small section of hair before applying it to the entire head. This helps to identify any potential allergic reactions, predict the final color result, or assess the strength of the chemical treatment on the hair. The test involves applying a small amount of the product to a small strand of hair, usually behind the ear or on the nape of the neck, and observing the results before proceeding with the full application.
